Fluorosilicone rubber is highly resistant to high and low

temperatures and solvents, and has excellent workability. In

IRM 903, a standard oil, there is less than 5% swelling

(150°C/70 h). Fluorosilicone rubber also has excellent resistance

to silicone fluid. Shin-Etsu’s fluorosilicone rubber products

include the FE-201-U Series for general molding (hardness:

25-80), and the FE-301-U Series of high strength rubbers

(hardness: 40-80). We also produce FE-451-U, a copolymer

type that exhibits oil resistance midway between that of

dimethyl silicone rubber and fluorosilicone rubber. This

copolymer material has oil resistance while also having superior

cold resistance, and maintains a greater degree of rubber

elasticity at low temperatures than typical silicone rubbers.

Applications : Rubber parts including diaphragms, check valves,

and connectors, specifically in applications requiring oil and

solvent resistance.

SEP rubber is produced by modifying ethylene propylene rubber

(EPDM) with silicone. This improves EPDM’s properties of heat

resistance and weather resistance, and low temperature

characteristics. These performance characteristics lie between

those of EPDM and silicone rubber, but SEP rubber has the

additional favorable properties of chlorine resistance and sponge

foaming characteristics. In high temperature conditions over

100°C, SEP rubber has higher mechanical strength, in particular

tear strength, than EPDM, and is comparable to high-strength

silicone rubber. In terms of resistance to steam, hot water, acids

and alkalis, SEP rubber is more durable than silicone rubbers.

SEP rubbers are available in several grades: general grade

(SEP-1711-U), heat-resistant grade (SEP-1721-U), extrusion

grade (SEP-1731-U) and flame-resistant grade (SEP-363-U).

Applications : Rubber parts for high-temperature applications

requiring high strength, including plug boots.

Shin-Etsu’s silicone rubbers typically do not include a curing

agent. These are called “U-types,” and expressed such as

KE-951-U. With U-type products, choose a suitable curing

agent (from C-1A to C-25A/B) in accordance with the curing

method. We also offer curing agents other than those listed

here. Please contact Shin-Etsu for details.

★ Note: Please contact Shin-Etsu separately for information regarding Hot Air Vulcanization (HAV).

✽1 C-4 is volatile, so the silicone rubber should be used soon after mixing.

✽2 C-8 has qualities nearly identical to C-4, but has the advantage of lower volatility than C-4.

Standard addition quantity is the quantity of curing agent added to 100 parts compound.

✽1 Curing may be uneven in molded items thicker than 5 mm. Shin-Etsu recommends C-3, C-8, or C-8A for molding items over 5 mm thick.

✽2 Molding possible at temperatures as low as 120°C-150°C.

By applying the primer in advance, better adhesion will be obtained.
